Subject: ipgre rss is broken since gro

Hi  Eric,

I'm trying to use GRE with RSS, but it looks broken on net-next since:

60769a5dcd8755715c7143b4571d5c44f01796f1 is the first bad commit
commit 60769a5dcd8755715c7143b4571d5c44f01796f1

    ipv4: gre: add GRO capability

    Add GRO capability to IPv4 GRE tunnels, using the gro_cells

    Tested using IPv4 and IPv6 TCP traffic inside this tunnel, and
    checking GRO is building large packets.

Multiple TCP streams over the tunnel cause (almost) immediately GRE interface to drop any ingress packet.

Please note that at current net-next head behavior is different - I hit null pointer dereference, I will try to bisect this behavior too.
